[PATCH 0/10] pull request (net): ipsec 2026-07-10

1) xfrm: propagate -EINPROGRESS from validate_xmit_xfrm()
   Return -EINPROGRESS from xfrm_output_one when validate_xmit_xfrm
   requeues the packet asynchronously, so the caller doesn't treat it
   as a real error and free the skb.

2) xfrm: fix stale skb->prev after async crypto steals a GSO segment
   Re-derive skb->prev from the fragment list after async crypto splits
   a GSO skb, keeping the linked-list pointers validi.

3) xfrm: nat_keepalive: avoid double free on send error
   Hold a state ref while the nat_keepalive timer is active and drop the
   timer before freeing the state, preventing a re-entered free on send
   error.

4) xfrm: fix sk_dst_cache double-free in xfrm_user_policy()
   Null the skb dst cache before freeing the policy so a later skb
   destructor doesn't double-free it.

5) xfrm: cache the offload ifindex for netlink dumps
   Cache the device ifindex at state-add time and use it for netlink
   dumps instead of dereferencing dst->dev, which may have changed by
   the time the dump runs.

6) xfrm: reject optional IPTFS templates in outbound policies
   Reject outbound policies with an optional IPTFS template,
   IPTFS must always be used if configured.

7) xfrm: clear mode callbacks after failed mode setup
   Clear the mode->init_flags and init_state callbacks on the error path
   after xfrm_init_mode fails, so a partially-initialised mode isn't
   reused in xfrm_state_construct.

8) xfrm: iptfs: propagate SKBFL_SHARED_FRAG in iptfs_skb_add_frags()
   Propagate SKBFL_SHARED_FRAG from the original skb to fragments
   allocated by iptfs_skb_add_frags, keeping shared-fragment accounting
   correct after IPTFS reassembly.

9) xfrm6: clear dst.dev on error to avoid double netdev_put in xfrm6_fill_dst()
   Clear dst->dev on the error path of xfrm6_fill_dst() so the caller
   doesn't release the netdev reference twice via dst_release.

10) xfrm: policy: preallocate inexact bins before xfrm_hash_rebuild reinsert
    Preallocate all inexact hash bins before existing entries are
    reinserted during xfrm_hash_rebuild, so reinsertion always hits an
    existing bin.

Please pull or let me know if there are problems.

Thanks!
